Ninety‐eight isolates of Rhizoctonia spp. were obtained from barley and wheat grown in Erzurum, Turkey. Of these, 78% were Rhizoctonia solani (AG‐2 type 1, AG‐3, AG‐4, AG‐5 and AG‐11), 10% were binucleate Rhizoctonia (AG‐I and AG‐K) and the remainder were Waitea circinata var circinata ( Rhizoctonia sp.). Among the binucleate Rhizoctonia , AG‐I was not recovered from barley. In pathogenicity tests on barley and wheat, the highest disease severity was caused by isolates of AG‐4 and AG‐11, whereas isolates of AG‐2 type 1, AG‐3, AG‐5 and W. c . var circinata were moderately virulent. Isolates of binucleate Rhizoctonia were all nonpathogenic. This is the first report of R. solani AG‐11 and W. c . var circinata from Turkey.
